Looking down, trying to figure out why his cock sometimes takes over and makes him do things he does not want to.  It gets him into trouble.  It makes him say things he does not mean.  It will do anything to make sure it can sink deep into a tight hole and blow a load.  It’s like he has no control of it, once it gets an idea in it’s little head.  

Take last night, for example.  He knew it was a bad idea, he knew he should not do it, but, once again, his cock took over and made him cunt his drunk roommate. He came home and saw his roommate passed out on his bed with his tight ass sticking up in the air.  His cock suddenly grew to full size and started telling him that fucking his roommate would be a good idea.  It started talking to him, rationalizing the idea of ramming into his tight hole.  Before long he had unzipped and let the big guy out.  He leaned over and pulled down his roommates boxers. His cock was throbbing and letting him know how great it would feel to punch into that hairy ass. It started telling him that his roommate was asking for it.  If he did not want to be fucked, he would not be laying there with his ass exposed.  

Now his cock had come to life again, It was telling him that since his roommate, had taken his load last night, it would be willing and able to take it again every night.  His cock was giving him the idea that his roommate would be an excellent cum dump for him for the rest of the semester.

Occasionally the ideas his cock has, are good ones.
